UUN1A471MNQ1MS

The UUN1A471MNQ1MS is a chip‑type, bi‑polar aluminum electrolytic capacitor designed for surface mounting on high‑density PC boards. It delivers 470 µF at 10 V in a compact SMD can package and is intended for general‑purpose electronic designs that require a wide operating temperature range and robust ripple handling.

Built for automated assembly and long operating life, this RoHS‑compliant capacitor supports designs that demand stable performance from −55°C to +105°C and endurance of 2000 hours at +105°C.

Key Features

• Bi‑Polar Construction  Bi‑polarized design removes polarity constraints for reversible or AC‑paired applications and supports operation across −55°C to +105°C.
• Capacitance & Voltage  470 µF nominal capacitance with a rated voltage of 10 V and a tolerance of ±20% (at 120 Hz, 20°C).
• Ripple Performance  Rated ripple current of 340 mA at 120 Hz and 510 mA at 10 kHz to address low‑ and high‑frequency ripple conditions.
• Endurance  Specified for 2000 hours at 105°C with polarity inversion every 250 hours as part of the series endurance characterization.
• Surface‑Mount Chip Package  Chip‑type, radial can SMD package optimized for high‑density PCB layouts; recommended land size: 12.8 mm × 12.8 mm.
• Manufacturing Compatibility  Applicable to automatic mounting machines fed with carrier tape to streamline high‑volume assembly.
• Environmental Compliance  RoHS‑compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Electronics  Provides bulk capacitance in compact surface‑mount assemblies where 470 µF at 10 V is required.
• High‑Density PCB Assemblies  Chip package and SMD format are suited for densely populated boards and automated placement workflows.
• Temperature‑Sensitive Systems  Wide −55°C to +105°C operating range supports applications exposed to broad ambient temperature swings.

Unique Advantages

• Reversible Polarity Flexibility  Bi‑polar construction reduces design constraints when polarity reversal or bipolar operation is present.
• Compact High Capacitance  470 µF in a chip‑type SMD can enables higher energy storage in a small PCB footprint.
• Measured Ripple Ratings  Provided ripple current values at 120 Hz and 10 kHz allow designers to match capacitor selection to expected operating frequencies.
• Long‑Term Reliability Data  Endurance specified at 2000 hours at 105°C gives a quantifiable metric for thermal stress planning and lifetime estimation.
• Assembly‑Friendly Packaging  Carrier‑tape compatibility supports automated placement for efficient, repeatable manufacturing.
• Regulatory Compliance  RoHS conformity simplifies materials compliance for commercial and industrial products.
